3/8in Moly Pushrods - 9.350in Long

The 3/8in Moly Pushrods – 9.350in Long by MANLEY are precision engine components designed for high-performance marine and automotive applications where reliability under load is non-negotiable. Built for serious boaters and engine builders who demand durability, these chromoly pushrods transfer valve actuation from the cam to the rocker arm with minimal flex and maximum consistency. Whether you're rebuilding a freshwater fishing rig's powerplant or upgrading a performance cruiser engine, quality pushrods are the silent foundation of predictable throttle response and long service life.

Manufactured from chromoly steel, these pushrods feature a 3/8-inch diameter with 0.080-inch thick walls and swedged ends that seat securely in both lifter and rocker arm cups. Chromoly construction delivers superior strength-to-weight ratio compared to standard steel, resisting bending and fatigue under the repeated high-speed cycles that marine engines endure—especially in performance tuning scenarios. The 9.350-inch length is precision-engineered to maintain exact valve timing geometry; even fractional deviations compromise cam timing and cylinder head sealing, so OEM-spec fitment is critical. Set of 8 ensures you have complete coverage for a full engine rebuild.

These pushrods are ideal for engine rebuilders, performance marine technicians, and experienced DIY boaters undertaking a complete engine refresh. Compatibility depends on your specific engine block and head configuration; always verify bore diameter and installed length before purchase. Installation requires proper valve lash adjustment and careful inspection of rocker geometry to prevent binding. Stock these alongside your gasket sets and cam components when planning a major marine powerplant rebuild—they're the kind of foundational upgrade that compounds reliability across the entire valvetrain.
